WASHING-MACHINE.

Speceaton of Letters Patent No. 10,219, dated November 8, 1853.

To all whom t may concern Be it known that I, JOEL VISNER, of Aurora, inthe county of Erie and State of New York, have invented a new and usefulImprovement in lVashing-Machines; and I do hereby declare that thefollowing is a full, clear, and exact description of the constructionand oper-ation of the same, reference being had to the annexed drawings,forming part of this specification, in which- Figure l is a top view ofthe machine with rubber removed. Fig. 2 is a vertical section ofcomplete machine, on line a2-w of Fig. l. Fig. 3 shows a cross sectionof radial ribs f and m taken on line g/-g/ Fig. 2.

Similar letters indicate like parts of the machine.

The nature of my invention consists in 'constructing the interiorsurface of the bot tom of the tub, and underside of the rubber, withradial ribs in the form of semi-frusw tums of cones, with their largerbases toward the exterior' of the tub and perimeter of the rubber; theunder surface of the rubber being beveled outward and upward, so thatthe elements of the ribs on both rubber Vand bottom, which are farthestfrom said surfaces, will be parallel when the ribs have the positionshown in Fig. 3, forming elements of concentric conical surfacesrespectively parallel to each other: the effect being to furnish spacefor the clothes between the ribs, and to prevent their drawing towardthe center of the machine, and otherwise to facilitate the cleansingprocess, by causing the clothes to move toward the perimeter of the tuband at the same time turn them over in the spaces between the ribs, asthe rubber is rotated, which effect diifers from that produced in othercircular wash tubs having rotating rubbers, as I have found by longexperience in the use ofwashtubs of this character and which rendersthis machine superior to others in use.

In the drawing B is the tub and C the. rubber, the bottom a of theformer and under surface of the latter having the radial ribs f and m,consisting of semi-frustums of cones with their larger bases toward thesides of the tub; the under surface of the rubber being so beveled as tobring the outer element of the rib fm, parallel to the correspondingelement of any rib f directly beneath it; or, to make the surfacesgenerated by the revolution of said elements about the axis of therubber and tub parallel to each other. Through the middle of the tubpasses the spindle F, having on it the seat G, which limits the descentof the rubber. From the top of the rubber arise the standards It, acrosswhich is the beam I-I, perforated in its center to receive the spindleF.

The operation of my machine is as fol lows: The clothes to be washedtogether with the requisite quantity of water and soap, are deposited inthe tub and the rubber pla-ced upon them, by passing the opening in itscenter, and the perforation in the beam H over the spindle F. Theoperator then grasps the handles T of the beam H, and causes the rubberto perform alternate semirevolutions about the spindle F, the weight ofthe rubber and the motion given to it causing the ribs upon the rubberand bottom, to press, rub, and agitate the clothes suiiicient to removetheir impurities without injury to their texture.-

This construction of ribs and rubber differs from t-he iiuted rubbersand bottoms in ordinary use, inasmuch as the space between the rubberand bottom of the tub, is greatest at the periphery of the rubber,giving the clothes a tendency to the sides of the tub, instead ofdrawing them to the spindle, where they will receive but littleagitation and are liable to be Cut. This machine for simplicity ofconstruction and facility of operation is superior to most washingmachines in use, and only requires a test to render its merits apparent-I do not claim in general the use of a horizontal circular rotarywashboard in the bottom of a wash tub when they are used with theordinary radial iiuting, as such has been long known, but what I doclaim is the following, viz:

Making the said wash board of a conical form having its surface higherabove the bottom of the tub at the circumference than at the center, andattaching to it and to the bottom of the tub radial ribs of the form ofa half cone, when these ribs are formed of such depth, and with spacesso wide between them, as to receive the clothes in those spaces in suchmanner as to turn or roll them over as the board is rotatedv back andforth, as above described.

In testimony whereof, I have hereunto signed my name before twosubscribing witnesses.
